Noise is almost impossible to compress, so I think what happened was that the bitrate spiked so much during this scene, that it blew the bit reservoir, causing the encoder to increase quantization so much it blurred the video too much. For typical bitrates, when I use VBR with max bitrate a little over 2X average bitrate, and 25 second buffer, I have not really seen this happen, but can't remember any scenes like this either. There is no adjustable post-processing in RV9, so I think the problem occured on the encoder side.
With regards to encoding tools, AutoRV9 uses Helix Producer as its back-end, but it is a great help in automating the process.
will do, thanks. I'll have to get a good source to test with.

also, in autoRV9, it has options for "normal video" "smooth video" and "sharpest video".. I always use sharpest, but what exactly does puitting it on normal or smooth do? does it pre-process the source?
